JBL The 7+13 balls - FAQ

I would like to fertilise my plants with your product and change over completely. How do I go about doing that?

Generally, one should never change plant fertilizers abruptly. The fertilizers from different manufacturers have somewhat different compositions in terms of trace elements. This may cause temporary nutrient changes. It is best to change over in 3 steps:

1) Reduction of the old fertilizer by 1/3; replace this with 1/3 of the new fertilizer. Wait approx. 3-4 weeks and observe the reaction of the plants.
2) Reduction of the old fertilizer by 2/3; replace this with 2/3 of the new fertilizer. Wait approx. 3-4 weeks and observe the reaction of the plants.
3) Complete discontinuation of the old fertilizer and change-over to the new fertilizer.

It is important to observe the reaction of plant growth and, in addition, to check the iron content of the water at least 2x weekly. Whereas the value should never drop to 0, it should never exceed 0.2 mg/l if possible. However, short peaks are no cause for concern. These measures should generally be carried out on a weekly basis, ideally right after a water change. This achieves better results than fertilizing in large doses at longer intervals.

I can't get all of the pellets out of the tank. Is that harmful to my fish?

The pellets don't contain any heavy metals, so that they are not toxic to fish. Therefore, there is no need for concern if a pellet or two stays in the tank.

If I am using JBL 7 pellets, does it make sense to also fertilise with JBL Ferropol ?

Yes, that makes sense and may even be advisable, depending on the plants in the aquarium. The JBL 7 pellets are intended more for root feeding plants and supply the plants with nutrients via their roots. Using JBL Ferropol and the water column to fertilise is generally advisable, as all plants, including the root feeding plants, also absorb nutrients through their leaves.

Are fertiliser pellets (JBL 7 Balls) harmful for my invertebrates such as shrimp and crustaceans?

JBL 7 Balls are harmless to shrimp. It's worth noting that the commonly held notion of shrimp being sensitive to copper is not correct. What is true is that shrimp even need copper urgently as a trace element for their blood pigment (haemocyanin). When using a standard fertiliser, one must overdose 80-100 fold in order to reach the ranges that are dangerous for shrimp, or a copper overdose as applicable. The situation is quite different when it comes to copper-based medications or algae control products, as these have much higher doses.
